摘　　要：目的:探讨多发脑膜瘤的影像学特点。方法:对27例经术后病理确诊的多发性脑膜瘤患者术前影像学等临床相关资料进行回顾性分析。结果:本组27例中,共58个病灶,颅内病灶最多的共有14个,最少的共有2个,显示大脑凸面肿瘤数27个,大脑镰13个。肿瘤实体直径最小为0.5 cm,最大为8.5 cm,平均4.5 cm。其中78%(21例)发病模式为一个较大肿瘤和许多较小肿瘤,仅有6例为大小相似的2个或多个肿瘤,并且肿瘤总数均小于5个,数目较多的肿瘤为"子母瘤"的形式。结论:多发脑膜瘤的数目、大小差别较大,既可集中分布,亦可分散存在,无论是多排增强CT还是高场强MRI诊断均应全面观察,避免遗漏。Objective： To investigate the imaging features of multiple meningiomas （MM）. Methods： The preoperative imaging clinical information of 27 cases of MM confirmed by surgery and pathology were.retrospectively analyzed. Results： In 27 patients with MM involved in this research, a total of 58 lesions, intracranial lesions up to a total of 2-14, 27 cases were in the brain convexity, 13 cases were in the brain falx. The tumor entities minimum diameter was 0.5 cm, a maximum of 8.5 cm, an average of 4.5 cm. Mode of onset of 78 % （21 cases） was a larger tumor and many smaller tumors, only 6 cases was showed similar in size to two or more of the tumor, and the tumor was less than the total number of 5, a larger number of tumor Picture-in the form of the tumor. Conclusion： Both the number and size of multiple meningiomas were greatly different. It could be concentrated or dispersed, to diagnosis of MM, either multi-row enhanced CT or high field strength MRI should be fully observed to avoid missing.
